Detailed Description

To facilitate understanding of the present invention by those skilled in the art, the present invention will be further described with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Fig. 1 to 5 schematically show the utility model discloses a high-power paster LED lamp pearl of thermoelectric separation formula.

As shown in fig. 1 to 5, the utility model discloses a high-power paster LED lamp pearl of thermoelectric separation formula includes support 1, chip 2, support pin 3 and wire 4.

The support 1 is provided with a heat dissipation bottom plate 5, the heat dissipation bottom plate 5 comprises an upper surface 51 and a lower surface 52, and both the upper surface 51 and the lower surface 52 of the heat dissipation bottom plate 5 are exposed relative to the support 1. The chip 2 is disposed on the upper surface 51 of the heat-dissipating substrate 5. The heat generated by the chip 2 is radiated outward through the heat-radiating bottom plate 5. Preferably, the chip 2 is attached to the upper surface 51 of the heat dissipation base plate 5 by using a thermally conductive die bond 6. The heat-conducting solid crystal glue 6 can reduce the thermal resistance and accelerate the heat conduction of the chip 2. Preferably, the thermally conductive die bond paste 6 is selected from silver paste or tin paste. The heat generated by the chip 2 is conducted to the heat dissipation bottom plate 5 through the heat conduction die bond 6 and dissipated outwards. The chip 2 includes a red chip 7, a green chip 8, a blue chip 9, and a white chip 10. The upper surface 51 of the heat dissipation bottom plate 5 is provided with an RGB area 511 and a W area 512, the red light chip 7, the green light chip 8 and the blue light chip 9 are arranged in the RGB area 511, and the white light chip 10 is arranged in the W area 512, so that the light emitting color of the LED lamp beads is more diversified. Preferably, the red chip 7, the green chip 8, the blue chip 9 and the white chip 10 may adopt a high power specification.

The bracket pins 3 are fixed in the bracket 1 and extend to the two outer sides of the bracket 1. The support pins 3 are connected to the chip 2 by wires 4. From this, realize support pin 3 and radiating bottom plate 5's disconnect-type setting, make electric region and heat dissipation region mutually independent, increase heat radiating area, prolong the life of lamp pearl. Support pin 3 is eight and sets up in 1 both sides of support symmetrically, makes things convenient for the installation and the connection of LED lamp pearl. Preferably, the wire 4 adopts the gold thread, and the gold thread has stable performance's characteristics, makes the long service life of wire 4 to improve the life of LED lamp pearl.
